The results and analysis of photometric measurements for MWC 342 are given. The photometric BVRI dates were received with CCD camera ST-7 and filters of SBIG. In spite of that R and I filters gives the magnitudes in Johnson-Cousins system, we reduced our observations to the standard Johnson system. All photometric observations were corrected for flat field, received from twilight sky.The cyclic changes of brightness with the period P=5588 of days are found. It is shown that on separate intervals of time the periodic changes with the period 115 days are possible but it is difficult to draw a conclusion about reality of cycle brightness variations on periods 100-200 days.References
